The U.S. Census Bureau has released an Application Programming Interface (API) to enable developers to create applications for the web and mobile platforms to enable users to explore census data via customized interfaces. The API enables developers to access the 2010 Census (Summary File 1) and the 2006-2010 American Community Survey (ACS) 5 Year Estimates allowing users to view data on population, age, sex, race, Hispanic origin, households, education, income, employment, commuting, occupations, housing, and more.
The U.S. Census Bureau has developed an “App Gallery” which will feature applications developed using the API. Currently there are two examples in the App Gallery that provide examples of the potential for using the Census API. These applications include:
- Age-Finder – enables users to count population for single years or for a range of customized age ranges.
- Poverty Map – provides poverty statistics from the American Community Survey for New York state and includes an visualization of margin of error and more.
Want to explore the Census API and develop your own application? Developers can access the Census Bureau API at: http://www.census.gov/developers/. Have an idea for an application using the API? Share your ideas through the Census Bureau’s Developers Forum.
Try out the Census Bureau API and if you create something be sure to share it with the U.S. Census Bureau. Enjoy!
The Cornell University Program on Applied Demographics (PAD) website possesses some great Census related resources. The first is a margin of error calculator for American Community Survey data which was created based on this U.S. Census Bureau document. The calculator allows you to enter values and operations in order to compute new margins of errors or test for significance of the difference between values.
Second, if you are looking for maps of current demographic data for the state of New York, then this site’s Census 2010 Atlas will be especially helpful. It has an easy to use index that allows users to choose what map to display. Once the map is displayed you can easily download a professionally prepared map in the form of a JPEG file.
The PAD website also has additional resources including white papers, presentations and more.

The U.S. Census Bureau will hold a webinar on the new data delivery tool, American FactFinder. During this comprehensive 30-minute tutorial, an expert on the use of American FactFinder will demonstrate how to locate, access, manipulate, map and download Summary File 1 for states and other previously released 2010 Census data.
The webinar will consist of a simultaneous audio conference and online presentation. Reporters will be able to ask questions during the audio conference once the tutorial is complete.

Next week, the U.S. Census Bureau will release the 2010 Census Summary File 1 for Alaska, Colorado, Connecticut, Nebraska and North Carolina. During June through August, the Census Bureau will provide statistics for states each week on a flow basis. These Summary File 1 tables will provide the most detailed information available so far from the 2010 Census, including cross-tabulations of age, sex, households, families, relationship to householder, characteristics of owners and renters, detailed race and Hispanic or Latino origin groups, and group quarters.
The Summary File will be available for each of the 50 states, the District of Columbia and Puerto Rico. The information will be available for a variety of geographic areas, with most tables available down to the block or census tract level.
The Summary File 1 for these states will be available on an embargoed basis for accredited media who are registered for access on Tuesday, June 28 at 10 a.m. The embargo will be lifted and the information released publicly on Thursday, June 30 at 12:01 a.m.
To apply for embargo access, go to our Newsroom at <http://www.census.gov/newsroom> and click on “Embargoed Releases.” Please review the Embargo Policy carefully before submitting the embargo registration form.

Are you interested in learning more about using the New American FactFinder to access data from the 2010 U.S. Census? The Connecticut State Data Center is offering a series of workshops across the state to provide users with an opportunity to learn more about the New American FactFinder in a hands-on workshop environment. Included below are the upcoming workshops, and we will be offering additional workshops at more locations soon.
Locating Census 2010 Data using the NEW American FactFinder
The U.S. Census Bureau introduced a NEW American FactFinder online Census data tool with enhanced searching and data display capabilities in conjunction with the release of 2010 Census data. In this workshop you will learn how to use the new American FactFinder to locate and download data – and create thematic maps – from a wide variety of population, economic, and housing information in the 2010 and 2000 decennial Censuses. From information on individual neighborhoods or zip codes, to state- or national-level data, the new American FactFinder is a powerful tool for navigating the vast amounts of data made available by the U.S. Census Bureau. The new American FactFinder will also soon replace the legacy American FactFinder as the platform for retrieving data from the American Community Survey (the ongoing Census program which produces data on educational attainment, income, occupation, marital status, and other detailed social and economic characteristics), and will also deliver data from the Economic Census. Join us to learn more about how to effectively navigate the NEW American FactFinder.
